AIMS AND CONTENT LEARNING OUTCOMES The course aims to provide the student with basic knowledge on the motion of fluids. Such knowledge will be applied to the solution of hydrodynamic problems in global form and to the design and verification of simple hydraulic systems. AIMS AND LEARNING OUTCOMES The aim of the course is to provide the student with basic knowledge on the motion of fluids. At the end of the course the student will have acquired knowledge that will make him able to: calculate the action of a fluid at rest on surfaces and bodies inside it solve problems related to simple duct systems use the principles formulated in global form for the calculation of the action of a moving fluid on surfaces and bodies inside it. PREREQUISITES Have a solid understanding of the topics covered in the courses GENERAL PHYSICS and MATHEMATICAL ANALYSIS I. TEACHING METHODS The teaching is divided into lectures held by the teacher, in which the theory will be exposed and exercises. In the lectures, the theory will be applied to different examples. In the part devoted to exercises, the student will carry out independently exercises proposed by the teacher. The exercises will be corrected in the classroom by the teacher. SYLLABUS/CONTENT Fundamentals: The Continuum assumption. Physical properties. Forces acting on a fluid. Pressure and stress in fluids. State equation. Nonflowing fluids: Stress in a fluid at rest. Integral and differential equations for a fluid at rest. Pressure distribution in a constant density fluid subject to gravity. Pressure forces on plane surfaces. Pressure forces on curved surfaces. Pressure variation across plane interfaces. Kinematics of fluids: Eulerian and Lagrangian description of the flow. Material derivative. Velocity and acceleration. Transport Theorem. Fluid Dynamics: Stress in a moving fluid. Mass conservation principle and its integral formulation. Momentum principle and its integral formulation. Integral formulation of the angular momentum law. Applications of the integral formulation of fluid flow (Force of a jet on a surface). Ideal fluids and Bernoulli theorem with applications ( stagnation pressure, Pitot tube) Quasi-unidirectional incompressible flow: Characteristic quantities (averaged velocity, discharge, The Piezometric Head, Kinetic Head, Total Head).

The written test will be corrected immediately after the conclusion of the same. In order to access the oral part it is necessary to have passed the written test. The oral part will take place immediately after the correction and passing the written test. In order to take the exam of the course the student must have passed the exams of "GENERAL PHYSICS" and "CALCULUS I ASSESSMENT METHODS The written part of the exam is aimed at ascertaining that the student has acquired the necessary tools to solve simple problems of Hydrodynamics. The oral part is aimed at verifying the student's understanding of the course topics.
